Magnetic-field-induced critical dynamics in magnetoelectric TbPO
Christoph P. Grams, Markus Grüninger, Joachim Hemberger
We report on the magnetoelectric dynamics in the linear magnetoelectric antiferromagnet TbPO studied by broadband dielectric spectroscopy. For the phase transition into the mag…
Quasimolecular electronic structure of the spin-liquid candidate BaInIrO
A. Revelli, M. Moretti Sala, G. Monaco +16
The mixed-valent iridate Ba3InIr2O9 has been discussed as a promising candidate for quantum spin-liquid behavior. The compound exhibits Ir ions in face-sharing IrO6 octahe…
Evidence for current-induced phase coexistence in CaRuO and its influence on magnetic order
K. Jenni, F. Wirth, K. Dietrich +7
Combining quasistatic and time-resolved transport measurements with X-ray and neutron diffraction experiments we study the non-equilibrium states that arise in pure and in Ti subst…
Large positive magneto-conductivity at microwave frequencies in the compensated topological insulator BiSbTeSe2
Mahasweta Bagchi, Lea Pitz-Paal, Christoph P. Grams +6
The bulk electronic properties of compensated topological insulators are strongly affected by the self-organized formation of charge puddles at low temperature, but their response…
Domain dynamics in LiCuVO: Evidence for polarized nanoregions
Christoph P. Grams, Severin Kopatz, Daniel Brüning +5
LiCuVO is a model system of a 1D spin-1/2 chain that enters a planar spin-spiral ground state below its Néel temperature of 2.4 K due to competing nearest and next nearest neig…
Interplay between antiferrodistortive, ferroelectric and superconducting instabilities in Sr_{1-x}Ca_{x}$TiO_{3-δ}
B. S. de Lima, M. S. da Luz, F. S. Oliveira +11
SrTiO undergoes a cubic-to-tetragonal phase transition at 105K. This antiferrodistortive transition is believed to be in competition with incipient ferroelectricity. Substitu…
